Two-Dimensional Material-Reinforced Separator for Li–Sulfur Battery
Li–S batteries
are heavily researched as they are capable
of meeting the demands of electrification of transport systems, provided
their inherent polysulfide shuttling can be prevented to enhance the
cycle life. Although several approaches have been made to mitigate
the shuttling effect, success is limited due to the poor adsorption
capability of polysulfides on the cathode surface. Herein, we propose
an efficient approach of using two-dimensional materials with permanent
dipoles in the separator to inhibit mass transport of polysulfides
from cathode and subsequent parasitic reactions on the metallic lithium
anode. Two-compartment H-cell experiments coupled with spectroscopic
studies, such as ultraviolet–visible absorption, nuclear magnetic
resonance spectroscopy, and Fourier transform infrared spectroscopy,
are used to demonstrate the interactions between the two-dimensional
materials-modified separator and polysulfide species. Furthermore,
electrochemical properties reveal the excellent specific capacity
of 1210 mAh g<sup>–1</sup> and self-discharge studies suggest
the feasibility of modified separator for commercial applications
Mechanistic Study of Lithium-Ion Battery Cathode Recycling Using Deep Eutectic Solvents
The
colossal increase in the use of Lithium-ion batteries
(LiBs)
necessitates their efficient recycling to ensure a steady supply of
essential cathode materials, e.g., Li, Co, and Ni, as well as to tackle
huge bulks of battery waste. Deep Eutectic Solvents (DESs) are green
solvents with immense potential in the hydrometallurgical recycling
of LiB cathodes, although their leaching mechanism has not been explored.
We investigate the leaching mechanism of the different transition
metals (TM), e.g., Co, Ni, and Li, from the most abundantly used LiB
cathode materials NMC and NCA in an ethylene glycol (EG):choline chloride(ChCl)
based DES. Leaching experiments performed by altering different parameters
and density functional theory (DFT) calculations imply that EG participates
in H-bonding and weakens the metal–oxygen bond of the TMs,
whereas Cl– attacks the metal center to form chlorometalate
complexes. Li on the other hand is surrounded by Cl– ions and leached in the solution. The increased concentration of
ChCl in DES ensures the facile formation of these complexes and enhances
leaching
